Nebula Manager is a simple tool to create app shortcuts on your Android TV home screen for better customization.
Instead of using the App Drawer icon on the top left to access your normal(non AndroidTV apps), you can now use Nebula Manager to add those apps to the main homescreen of AndroidTV and display them as a channel.

Choose the apps you want to show on the homescreen.


See the bottom row on how app shortcuts would look like.

Previously you needed to use Sideload Channel Launcher for TV app to add app shortcuts to your home launcher main screen but this is a paid app, Nebula Manager is a free app.
I will also include this app in future Station P1/M1 AndroidTV firmwares.
